SWITCH-OPERATING DEVZCE.

Application filed September 7, 1927, Serial No. 217,967.

This invention relates to a device for operating electrical switches,especially but not necessarily of the push button type, and has moreparticular reference to means for operating the actuating elen'ient orpush button of a switch from a distance.

The primary object of the invention is to provide a device of the abovekind by means of which the necessity, of providing an e tension cordwith a switch on the free end thereof, is avoided.

A further object is to provide a device ct the kind specified which issimple and, durable in construction, and etiicient in operation.

The invention consists i the novel term, combination and arrang .ent ofparts hereinafter more fully described, shown in the accompanyingdrawing and claimed.

In the drawing,

Figure 1 is a view showing the use of the switch operating device inconnection with a wall switch of a bedroom, the device being in sideelevation.

Figure 2 is an enlarged fragmentary front elevational view of the switchand operating device shown in Figure 1, and

Figure 3 is a view of the device shown in Figure 2, partly in verticalsection and partly in side elevation.

Referring more in detail to the drawing, 5, indicates the wall of abedroom or a room in a hospital or the like, and in which is locatedthebed 6. in the wall 5 is mounted a con.- ventional form of two-buttonelectrical snap switch 7 having a button 8 adapted to be pressed toclose the switch and a button 9 adapted to be pressed to open the switchin a well known manner, the buttons being movable through. openings in asuitable face plat 10.

The present invention aims to provide means for operating the button 8or the like from a distance, as by the occupant of the bed 6.. for anysuitable purpose, such as for clos' in a cal -bell or other circuit. Forthis purpose, the face plate 10 is formed with a tubular boss 11 longerthan and housing the button 8, and threaded on the outer end of the boss11 is a tubular member 12 rigid with and provided between the connectedends of the legs of a li shaped bracket 13. A bell-crank RenewedDecember 3, 1828.

lever 14 is pivoted intermediate its ends to and between the lower freeends of the legs 15 of the bracket 13, and pivoted to the upper end ofthe lever 14 is the outer end of a push rod 16 which passes inwardlythrough the member 12 and enters the boss 11 to engage the outer end ofbutton 8. The lower arm of lever 1% projects rearwardly and has one endof a pull cord 1'! attached to the lower end thereof.

In view of the above, it will be seen that when an outward pull isexerted on the cord 1'? the button 8 will be pressed by plunger or rod16 to close the switch, and by extending the core. to the bed 6, theoperation may be effected by occupant of the latter. When the button 8is returned to its outward position, as by pressing on button 9 to openthe switch, the switch closing operation may be repeated. lit ispreferable to use a two-but ton snap switch for hospital use so that thenurse must answer the. call in order to operate the button 9 and openthe switch and the callbell or signal circuit controlled by the latter.

Minor changes may be made Without departing from the spirit and scope ofthe invention as claimed.

What I claim as new is:

1. The combination with a push button switch, of a face plate having atubular boss housing the push button of said switch, a bracket mountedon said boss, a lever pivoted to said bracket and having a pull memberat tached to one end thereof, and a plunger pivoted to the other end ofsaid lever and slidably projecting into the boss and in engagement withthe push button.

2. The combination with a two-button snap switch, of a face plate havinga tubular boss for housing the switch closing button, a plunger slidablein the boss, and a lever piv otally mounted on the boss and having oneend connected to said plunger, and a U- shaped bracket having a tubularmember rigid with and between the connected ends of the legs thereoftl'lreadcd on said boss, said lever being pivoted intermediate its endsto and between the tree ends of the legs of said bracket. y

In testimony whereof I aflix my signature.

CHARLES J. STEVENS.
